Two different shaped Ni-based metal–organic framework (MOF) nanosheets are prepared from hexagonal nickel hydroxide monolayer under the variable reaction conditions. The MOF with similar lateral size to Ni(OH)2 nanosheet is obtained on flat Si substrate but thickness increased 1 2 nm. Another rectangular when a carried out in solution which dispersed. difference shape of Ni-MOF related degree d...

Two-dimensional (2D) metal–organic frameworks (MOFs) have emerged as intriguing 2D materials because of their specific features morphology and designable skeletons, which elicited great interest in environment remediation. In this work, MOF nanosheets are fabricated via a mixed-solvent solvothermal method, regulation strategy metal inorganic clusters on MOFs is used to construct two different w...

Transmetalation is an innovative postsynthetic strategy for tailoring the properties of metal−organic frameworks (MOFs), allowing stable unprecedented metal coordination environments. Although the experimental synthetic protocol is wellestablished, the underlying mechanism for transmetalation is still unknown. In this work, we propose two different solvent-mediated reaction paths for the Ni tra...

By combining experimental adsorption isotherms, microcalorimetric data, infrared spectroscopy and quantum chemical calculations the adsorption behaviour of the CPO-27/MOF-74 series (Ni, Co, Mg, Cu, and Zn) in the desulfurization of fuels is evaluated. The results show a clear influence of the metal ion on the adsorption capacity and affinity for S-heterocyclic compounds, with CPO-27(Ni) being t...

Li adsorption on isoreticular MOFs with metal Fe, Cu, Co, Ni and Zn was studied using density function theory. Li functionalization shows a considerable structural change associated with a volume change in isoreticular MOF-5 except for the Zn metal center. Hydrogen binding energies on Li functionalized MOFs are seen to be in the range of 0.2 eV, which is the desired value for an ideal reversibl...

We present a method for approximating thermodynamic parameters ΔG(P,T)°, ΔH, and ΔS for the cation exchange process in metal-organic frameworks, as exemplified by Ni(2+) exchange into Zn4O(1,4-benzenedicarboxylate)3 (MOF-5) and Co(2+) exchange into MOF-5 and Zn5Cl4(bis(1H-1,2,3-triazolo-[4,5-b],[4',5'-i])dibenzo-[1,4]-dioxin)3 (MFU-4l). For these examples, we find that the cation exchange proce...

Porous graphitic carbon layers encapsulating Ni nanoparticles (Ni@C) were prepared by a facile thermolysis of a Ni-containing metal–organic framework, the structure of which were characterized by power X-ray diffraction (XRD), N2 adsorption–desorption, transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS) in detail. The resulting Ni@C nanocomposites served as highly...
